To recover an instant snap DCO volume
# vxsnap [-g diskgroup] dis snapvol
For the example output, the command would take this form:
# vxsnap -g mydg dis SNAP-vol1
# vxsnap [-g diskgroup] unprepare volume
For the example output, the command would take this form:
# vxsnap -g mydg unprepare vol1
# vxvol [-g diskgroup] start volume
For the example output, the command would take this form:
# vxvol -g mydg start vol1
# vxsnap [-g diskgroup] prepare volume [ndcomirs=number] \ [regionsize=size] [drl=yes|no|sequential] \ [storage_attribute ...]
For the example output, the command might take this form:
# vxsnap -g mydg prepare vol1 ndcomirs=2 drl=yes
The command adds a DCO volume with two plexes, and also enables DRL and FastResync (if licensed).
